            The cluster and attributes specified above are to be selected from the generated cluster objects.

            e.g.
                ReadAttribute(1, [ 1 ] ) -- case 4 above.
                ReadAttribute(1, [ Clusters.BasicInformation ] ) -- case 5 above.

            An AttributePath can also be specified directly by [chip.cluster.Attribute.AttributePath(...)]

        dataVersionFilters: A list of tuples of (endpoint, cluster, data version).

        eventNumberFilter: Optional minimum event number filter.

        returnClusterObject: This returns the data as consolidated cluster objects, with all attributes for a cluster inside
                             a single cluster-wide cluster object.

        reportInterval: A tuple of two int-s for (MinIntervalFloor, MaxIntervalCeiling). Used by establishing subscriptions.
            When not provided, a read request will be sent.
        fabricFiltered: If True (default), the read/subscribe is fabric-filtered and will only see things associated with the fabric
            of the reader/subscriber. Relevant for attributes with fabric-scoped data.
        keepSubscriptions: Keep existing subscriptions. If set to False, existing subscriptions with this node will get cancelled
            and a new one gets setup.
        autoResubscribe: Automatically resubscribe to the subscription if subscription is lost. The automatic re-subscription only
            applies if the subscription establishes on first try. If the first subscription establishment attempt fails the function
            returns right away.
